SPECIFICATION forming part of Letters Patent No. 667,402, dated February5, 1901.

Application filed August 9,1900. Serial No. 26,378. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LOUIS REICHERT, a citizen of the United States,residing at Scranton, in the county of Lackawanna, State ofPennsylvania, have invented certain new and useful Improvements inDevices for Adjusting Jewels in Watch-Pallets, of which the following isa specification.

My invention relates to a device intended for the use of jewelers andwatchmakers by means of which the jewels in watch-pallets of all thestandard forms may be` quickly and accurately adjusted. The variousmakers of watches employ pallets of a wide variety of designs and sizes,in each of which the jewels which engage the teeth of theescapementwheel must be accurately set. One of the most difficultoperations in repairing the variousstyles of watches is the operation ofresetting the pallet-jewels when they become displaced. The practice atpresent among watch-repair men is to heatthe pallet until the cement orshellac which` holds the jewels in place becomes softened, and then tomove the jewels in an experimental way until by trial they are finallybrought to the exact position. This operation is very tedious, oftenrequiring numerous trials and reheating of the pallet. By means of myimproved device the jewels in any one of a large variety of pallets maybe accurately adjusted in a few minutes and with very little difficulty.

In the accompanying drawings, which illustrate my invention, Figure I isa plan view of my improved adjusting device, and Fig. 2 is a perspectiveview of a portion of said device on an enlarged scale, illustrating themanner in which it is used to set the jewels in a watch-pallet; and Fig.3 is a longitudinal section through Fig. l.

In the drawings, A indicates a plate made of thin stiff metal and havinga series of open-- ings B therein, the walls of said openingscorresponding in general outline to the forms of various standard sizesand designs of pallets, such as are employed in the watches of variousman ufacturers. In the drawings I have shown only sixteen such openingsin the plate, but it will be understood that the plate may he iliadewith any greater or less number ofl openings as may be found desirable.The elongated part l of each opening is formed so that the anchor 2 of astandard pallet of corresponding form will exactly fit within it, asshown, and the pallet is prevented from passing entirely through theopening by the fork 3, which is secured to itand extends across theopening, resting upon the plate. The end walls 4 and 5 of the convergingarms 6 and 7 of the openings form stops ol gages for the jewels 8 and 9of the pallet. These walls are located accurately with reference to theanchor, so that when the jewels are forced outward in contact with themsaid jewels will be accurately positioned. When a pallet is placedwithin an opening, as shown in Fig. 2, a copper or other suitableheat-conducting strip IO is laid upon it, and the end of this stripextending beyond the plate is heated by means of a lamp l2. The heatconveyed through the wire to the pallet softens the cement, and thejewels may then be set out accurately against the stops and upon coolingthe pallet is ready for use. As shown in Fig. 3, the strip I0 has oneend l1 bent around the plate to hold it in position. The ystrip may beslid along the plate to cover any one of the /openings, and when laidacross the fork the pallet cannot drop out of the opening. By turningthe plate over after heating the strip the jewels may be set from theside of the plate opposite tothe anchorand heating-strip.

It will be seen from the foregoing description that a large saving intime is effected by means of this arrangement and that the device willbe found very useful in watch-repairing establishments where watches ofvarious makes are repaired.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is-

I. As an article of manufacture a device for adjusting the jewels inwatch-pallets consisting of a plate having a series of openings thereincorresponding in their general outlines to, and adapted to receive,dierent forms of pallets, the walls of said openings in front of thejewels being so located as to form stops or gages adapted to limittheoutward movement of thejewels when the latter are in proper position forworking, substantially as described.

2. A device for adjusting the jewels in watch-pallets comprising a platehaving a se- IOO of the plate and its opposite end extendingF beyond theopposite side of the pla-te.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS REIG/HEBT.
